You’ve got pretty big RTTs there (~6 seconds). It means the packets have “aged out” of the cache since the RTT is so long.

Thank you, do you have any suggestion to improve this, where this needs to be changed and what would be the impact?

Well, it could be because your bridge is far away from your participants, so deploying more bridges in more locations could help.

Thank you , but more worrying is the below error, the participant including the host is being disconnected when this error triggered.
